在输运数据可以定量地理解之前,必须满足一些先决条件:金属/分子接触的几何和电子结构必须是已知的,并且必须考虑电子相关效应。在这里,我们将讨论解决这些挑战的实验和理论方法。在理论方面,密度泛函理论(包括结构优化的货车德瓦尔斯修正)与多体微扰理论和数值重整化群理论相结合,以包括所有相关的关联效应。我们已经在之前的研究中讨论了这些特征[Phys. Rev. B84,125413(2011)],但是我们计算的光谱和我们从扫描隧道显微镜获得的实验数据之间的一些剩余差异仍然无法解释。在这里,我们表明,明确纳入货车德瓦耳斯相互作用的计算,已被取消之前,产生改进的几何结构,并导致更好的协议与我们的测量光谱。这清楚地表明了电子传输对结构细节的显著敏感性。PTCDA分子在银表面和STM针尖之间的结中。
Before transport data can be understood quantitatively, a few prerequisites have to be fulfilled: the geometric and the electronic structures of the metal/molecule contacts have to be known, and electron correlation effects have to be taken into account. Here we discuss experimental and theoretical approaches to tackle these challenges. On the theoretical side, density‐functional theory (including van der Waals‐corrections for structural optimization) is combined with many‐body perturbation theory and numerical renormalization group theory in order to include all relevant correlation effects. We had already discussed such features in a previous study [Phys. Rev. B84, 125413 (2011)], but some remaining differences between our calculated spectra and our experimental data from a scanning‐tunnelling microscope remained unexplained. Here we show that the explicit incorporation of van der Waals interaction in the calculations, that had been negleted before, yields improved geometric structure and leads to much better agreement with our measured spectra. This clearly demonstrates the significant sensitivity of electronic transport to structural details.PTCDA molecule in a junction between a silver surface and an STM tip.
